Social Security and Taxes: Coordinating Your Retirement Income

Retirement planning with James Mehok | Mehok Wealth Management

When should you start Social Security, and which accounts will fund the rest of your retirement spending? These questions belong in the same conversation. Your claiming decision changes your income, while withdrawals, taxes and healthcare costs help determine how much of that income is available to spend.

A coordinated plan considers your household needs and the tradeoffs among different choices. There is no single claiming age or withdrawal order that works for everyone.

Start with your income needs and benefit estimates

Social Security retirement benefits can generally begin at age 62, with a reduction for starting before full retirement age. Full retirement age is 67 for people born in 1960 or later. Delaying after full retirement age increases your retirement benefit through delayed retirement credits, which stop at age 70.

Compare your own estimates at different ages. Then consider health, expected longevity, work plans, available savings and the needs of anyone who depends on your income. Starting earlier can help meet current expenses; waiting means funding those expenses from other sources in exchange for a higher monthly benefit later. Neither choice guarantees a better lifetime outcome.

Understand how benefits can become taxable

Up to 85% of Social Security benefits may be included in federal taxable income. That does not mean an 85% tax rate. The calculation generally considers adjusted gross income, tax-exempt interest and half of your benefits, with adjustments under IRS rules. Filing status matters.

A taxable IRA withdrawal or Roth conversion can increase the taxable portion of benefits. Review the combined effect with your tax professional rather than looking only at the withdrawal's tax bracket.

Coordinate withdrawals instead of following a fixed order

Retirement spending may draw on cash, taxable investments, traditional retirement accounts and Roth accounts. The right mix depends on your expenses, tax situation, account rules and investment plan.

A lower-income period before Social Security begins may be a time to evaluate partial Roth conversions or planned withdrawals. It is not automatically a low-tax opportunity: pensions, business income, investment gains or a spouse's earnings may change the picture. A conversion creates current taxable income on previously untaxed amounts and may affect other benefits or costs.

Required distributions also deserve attention. Your age, account type and other circumstances determine the rules. Review current requirements with your tax professional and custodian; do not assume every retirement account follows the same schedule.

Explore whether a Roth conversion may make sense for you.

Consider your spouse and survivor needs

Couples should evaluate both earnings records and the income available after either spouse dies. Spousal and survivor benefits have distinct eligibility and claiming rules. A strategy that increases one person's benefit may also affect the household's future income options.

Review each person's estimates and confirm the applicable rules with Social Security. Rather than assume the higher earner should always wait or the lower earner should always claim early, compare household cash flow, health, age differences and available assets.

Include Medicare in the income picture

Higher income can increase Medicare Part B and prescription drug premiums through the income-related monthly adjustment amount, or IRMAA. Social Security generally uses tax information from two years earlier. A large withdrawal or conversion can therefore have consequences beyond the current tax year.

Delaying Social Security does not necessarily mean delaying Medicare. Review enrollment timing separately, including how current employer coverage affects your situation.

Check the details before accepting retroactive benefits

Eligible applicants may receive up to six months of retroactive retirement benefits, but not for months before full retirement age. Choosing an earlier start date can reduce delayed retirement credits compared with a later start.

Retroactive benefits can also complicate taxes. If a payment includes benefits for an earlier year, an IRS lump-sum election may reduce the taxable amount. Ask your tax professional to compare the available treatment before assuming all of the payment has the same tax effect.

A practical checklist for your planning conversation

Gather your estimates. Bring Social Security benefit estimates for you and your spouse, if applicable.
Map spending. Separate essential expenses from flexible goals and identify healthcare costs.
List income sources. Include employment, pensions and investment accounts.
Compare scenarios. Explore different claiming dates and withdrawal combinations, including how a surviving spouse would be supported.
Coordinate the tax review. Ask your CPA or tax professional to evaluate the applicable tax rules and filing consequences.
Revisit the plan. Update assumptions as your health, family needs, work and finances change.
